Problems Using Scientific Method Examples – 1.5 Define and identify examples of the following words related to the scientific method: observation, problem, hypothesis, experiment, independent variable, dependent variable, external variable, prediction, results, operation.
All scientific endeavors begin with observation. As curious creatures trying to understand the world around us, we have a natural tendency to notice patterns in naturally occurring situations and wonder “what the…” or “why?”.
Problems Using Scientific Method Examples
We gain insight into the villagers’ observations that left them wondering if the woman was a witch or not:
Solution: Scientific Method
The problem is the question you have about one or more observations. Problems often arise when you look at many things and organize them in some way. Based on your observations, you might ask “is there a pattern here?” (descriptive question), or “WHY does the pattern seem to exist?” (causal question).
You might think that the research problem in this example is simply, “Are you a witch?” This problem is a (probably) direct result of hard-to-explain behavior. He appears to be a witch (although some of the villagers admitted to dressing him as such), and he turned the man into a new one. But “Are you a witch?” descriptive question. Causal questions might include, “Why does he look the way he does?” or “Why are there more salamanders in his living room than usual?”
It is important to note that problems arise from observations that are not easily explained. They are based on observations.
Once a problem or question has been raised, it is common practice to make additional observations about the problem to help define, refine, or otherwise answer the problem. This may include library research on similar issues, or a formal collection of information about observed events that explain the problem. For example, if a person claims to have been turned into a witch because of the alleged witch’s actions (and powers), it would be a good idea to investigate whether anyone else has been similarly affected. Is someone claiming to have turned into a lizard? A small mammal like a vole or a muskrat? Does he really have more than normal salamanders in his living room? Such observations can help solve the problem.
What Is Design Thinking And Why Is It So Popular?
In standard scientific method models, this step is often poorly defined. Hypotheses are often described as ‘educated guesses’. Yes…it’s guesswork, but based on observation (the “educated” part of the phrase). In this case, there are only two different interpretations of the defining question “Are you a witch?”:
It is important to note that a hypothesis is NOT a prediction about the outcome (data) collected in the experiment. A hypothesis is used to MAKE a prediction, as shown in steps 6-7.
Again, the journey to answering questions about the natural world is deliberately designed. In the witch’s case, Sir Bedevere investigates the situation further by asking questions and gathering more information.
This is a real creative step in the scientific direction. Not all questions need to be answered with an experiment, but an experiment is one of the most direct ways to answer CAUSL (“why”) questions.
Problem Solving Strategies And Obstacles
In the example, an experiment is organized to test the hypothesis that he is a witch. So let’s assume the hypothesis is, “You’re a witch.” The test involves comparing its weight to that of a duck.
And based on the experimental design, a prediction is made about the data to be collected: the prediction is “If my hypothesis is true (the woman is a witch), then the woman weighs as much as the duck.” Note that the prediction is based on a theory, but it clearly describes what the data from the experiment should look like.
For this to be a good example of an experiment, it should be noted that these researchers should actually be measuring density, not weight. Density shows the size of an object compared to how much space it takes up. Anything with a density greater than water (one gram per cubic centimeter) will sink, and anything with a density below water will float. This is important, because a small duck probably won’t weigh more than anyone else, but an incredibly large duck can weigh more than Dwayne “The Rock” Johnson. So in this experiment, the independent variable (which is what the researchers did) would be the type of sample being measured (female or duck), and the dependent variable would be their density (or weight if their volumes were the same).
The only way their densities can be compared and measured with the same scale in the square is if their volumes are the same. This may be the most important external variable to check. External variables are any variables in an experiment that can influence the dependent variable, but you don’t want to be so sure that they are the same in all cases. Similarly, the weight of the platforms on which the duck and the female stand should be equal.
Introduction To Science Activity
This is the “data analysis” portion of the test. In the video, the data appears to match the prediction, and the hypothesis that she is a witch is supported (assuming the duck’s volume is the same as the woman’s).
Depending on the type of test and the validity of the recorded data, the woman can be said to be a witch.
But while this woman appears to weigh the same as a duck, closer examination and observation may confirm the truth of the entire claim that she is, in fact, a witch. More generally, further testing may be warranted to support the idea that women who weigh like ducks are, in fact, witches. Go back to step 1!
Variables manipulated or intentionally changed by researchers. These are variables that are believed to have a specific effect on one or more variables.
Scientific Method Study Guide Answer Key
A variable likely to be affected by the independent variable. In an experiment, this is the variable that changes due to the independent variable.
These variables can influence the dependent variable, but are of no interest to researchers and are therefore often best controlled within a study.

In the field of research (especially in science, including psychology), achievement represents the process of defining the measurement of a phenomenon that cannot be measured directly, although its existence is demonstrated by other phenomena . A good way to use variables is to define them based on the answers to the following questions:

An educational research project may contain dependent variables such as ‘student engagement’, ‘achievement’ or ‘positive attitudes’. The trick to using such variables is to define them in terms of how you know you have them and how much they are.
Variable performance is an important part of research design. During this course, you will notice that most important and well-known tests use specific and intelligent variables. This applies to some basic research conducted, but also to applied research studies. Since your research involves applied research methods and procedures, it is important to distinguish between basic and applied research. 2 Learning objectives Organize, explain and distinguish between the steps of the scientific method. Identify, describe and distinguish between the independent variable, dependent variable and control. Analyze and interpret the data collected from the survey. Display the collected data in a table or graph. Do a pill test. Distinguish between strong and weak example reports. Create a lab report using the lab report rubric.
Tadpoles in the cold aquarium weighed about 5 grams each. The tadpoles in the aquarium at room temperature weighed 7 grams each. Tadpoles in the warm aquarium weighed about 6 grams each. Details Deploy 3 small aquariums and place 5 tadpoles of the same species in each aquarium. In an aquarium, keep the water at room temperature. In the second aquarium, keep the water 10 degrees below room temperature. In the third aquarium, keep the water 10 degrees warmer than room temperature. After 3 weeks, weigh each tadpole. Test hypothesis Does water temperature affect tadpole growth? Objective The data did not support the hypothesis because the tadpoles in the aquarium with water at room temperature weighed too much. Conclusion Many species have suitable growing conditions. Frog mating times vary throughout the year. Observations When the water temperature drops, the growth of tadpoles will increase.
